03 APPLICATION NAME (monitor)
The name of the application.
Z**COMM PORT (MODBUS)**
This menu is used to setup the RS-422 serial port for use with Modbus.
01 ENABLE MODBUS CONTROL dflt = FALSE (TRUE, FALSE)
Set this value to TRUE to enable the Modbus Control command. If set TRUE, the
user will have MODBUS control over the discrete inputs, discrete outputs, the
Baseload Reference, and the Remote Speed reference. This value does not
have to be TRUE to view the other MODBUS variables.
When parameter 1 is set TRUE the analog inputs are disabled. If the
communication fails the speed setting/baseload setting will go to
minimum. The analog settings are not latched to the last value.
02 PORT 1 FAIL (monitor)
Indicates a hardware fault of the serial RS-232 communication port.
03 PORT 1 BAUD RATE dflt = 12 (8
–12)
Sets the Baud rate, which defines the transfer rate for port communications:
8 = 9600
9 = 19200
10 = 38400
11 = 57600
12 = 115200
04 PORT 1 BAUD RATE IS SET FOR: (monitor)
Shows the selected Baud rate.
05 PORT 1 DATA BITS dflt = 2 (1
–2)
Sets the Data bits input defines the protocol for the number of data bits in the
data packets:
1= 7
2= 8
06 PORT 1 DATA BITS ARE SET FOR: (monitor)
Shows the selected data bits.
07 PORT 1 STOP BITS dflt = 1 (1
–3)
Sets the Stop bits, which defines the number of stop bits for the communications
protocol. Stop bits specify the time that elapses between transmitted characters.
1= 1 stop bit
2= 2 stop bits
3= 1.5 stop bits
8 PORT 1 STOP BITS ARE SET FOR: (monitor)
Shows the selected stop bits setting.
9 PORT 1 PARITY dflt = 1 (1
–3)
Sets the Parity input defines protocol for the parity. If you selected 8 data bits
select '1' for none:
1= OFF (none)
2= ODD
3= EVEN
